9.Computer, software and laboratory information management system.
10. Using quality policy, quality objectives, audit results, analysis of data, corrective and preventive actions and management review to improve the effectiveness of management system continually.
||Initial test shall use immunoassay method. Where the concentration of drug or drug metabolite in the urine specimen are not lower than the following cutoff values, the specimen shall be judged as positive:
1.Amphetamines: 500 ng/mL.
2.Opiate metabolites: 300 ng/mL.
3.Marijuana metabolites: 50 ng/mL.
4.Cocaine metabolites: 300 ng/mL.
5.Ketamine metabolites: 100 ng/mL.
The initial test results of abused drugs or their metabolites other than listed in the preceding paragraph shall be determined according to the cutoff values in respect of the immunoassay method. In absence of suitable immunoassay method, other suitable analytical method may be adopted to conduct test with the support of proper detector, and the cutoff values may be determined appropriately according to the limit of quantification.
||Where the initial test results are lower than the cutoff values set forth in the preceding Article, the urine specimen shall be judged as negative; and the residual specimen shall be disposed in accordance with the provision of article 9.
||The testing institution may use two or more initial test methods to test a same kind of abused drug, and shall observe the provisions set forth in these Regulations.
||Where the initial test results are not lower than the cutoff values or any doubt arises about the test result of the urine specimen, gas chromatography/mass spectrometry method or liquid chromatography/mass spectrometry method shall be used to perform confirmatory test. If the test results are not lower than the following cutoff values, the specimen shall be judged as positive:
(1)Amphetamine: 500 ng/mL.
(2)Methamphetamine: Methamphetamine 500 ng/mL, and its metabolite amphetamine not less than 100 ng/mL.
(3)3,4-Methylenedioxymethamphetamine (MDMA): 500 ng/mL. If both MDMA and MDA are found and the concentration of each is lower than 500ng/mL, but the total concentration is not lower than 500 ng/mL, the specimen shall also be judged as MDMA positive.

(2)Norketamine: 100 ng/mL.
For the abused drugs other than listed in the preceding paragraph or other metabolites, proper cutoff values may be set forth according to the limit of quantification in respect of the gas chromatography/mass spectrometry method or liquid chromatography/mass spectrometry method.
||Where the confirmatory test results are lower than the limit of quantification set forth in the preceding Article, the urine specimen shall be judged as negative; and the residual specimen shall be disposed in accordance with the provision of article 9.
||For the drug abuse urine used for juridical cases, the limits of quantification may be used as cutoff values where necessary, without being limited by the provisions of Articles 15 and 18.
||The test report shall be produced by the testing institution in writing.
||Where necessary, the test consignor may request the testing institution to provide original test records or test results.
||If the test consignor doesn't agree with the result of urine test, it may explain the reasons to request retest within fourteen days following receipt of test report.
||The limit of quantification of abused drugs or their metabolites tested by the testing institution shall be used as the basis of the cutoff values for retest of urine specimens. Where the retest result are lower than the limit of quantification, the specimen shall be judged as negative; where not lower than the limit of quantification, positive.
